GENERAL SAFETY RULES
WARNING!
Read all instructions
Failure to follow all instructions listed below may result in
electric shock, fire and/or serious injury.
The term “power tool” in all of the warnings listed below
referstoyourmainsoperated(corded)powertoolorbattery
operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
1) Work area
a) Keep work area clean and well lit.
Cluttered and dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of flammable
liquids, gases or dust.
Power tools create sparks which may ignite the
dust of fumes.
c) Keep children and bystanders away while operating
a power tool.
Distractions can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet.
Never modify the plug in any way.
Do not use any adapter plugs with earthed
(grounded) power tools.
Unmodified plugs and matching outlets will reduce
risk of electric shock.
b) Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators.
There is an increased risk of electric shock if your
body is earthed or grounded.
c) Do not expose power tools to rain or wet
conditions.
Water entering a power tool will increase the risk
of electric shock.
d) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts.
Damaged or entangled cords increase the risk of
electric shock.
e) When operating a power tool outdoors, use an
extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces
the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired or
under the influence of drugs, alcohol or medication.
A moment of inattention while operating power
tools may result in serious personal injury.
b) Use safety equipment. Always wear eye protection.
Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal
injuries.
c) Avoid accidental starting. Ensure the switch is in
the off position before plugging in.
Carrying power tools with your finger on the
switch or plugging in power tools that have the
switch on invites accidents.
d) Remove any adjusting key or wrench before
turning the power tool on.
A wrench or a key left attached to a rotating part
of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance
at all times.
This enables better control of the power tool in
unexpected situations.
f) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts.
Loose clothes, jewellery or long hair can be caught
in moving parts.
g) If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used.
Use of these devices can reduce dust related hazards.
4) Power tool use and care
a) Do not force the power tool. Use the correct
power tool for your application.
The correct power tool will do the job better and
safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not
turn it on and off.
Any power tool that cannot be controlled with the
switch is dangerous and must be repaired.
c) Disconnect the plug from the power source before
making any adjustments, changing accessories, or
storing power tools.
Such preventive safety measures reduce the risk
of starting the power tool accidentally.
d) Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool.
Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power
tools operation.
If damaged, have the power tool repaired before
use.
Many accidents are caused by poorly maintained
power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
g) Use the power tool, accessories and tool bits etc.,
in accordance with these instructions and in the
manner intended for the particular type of power
tool, taking into account the working conditions
and the work to be performed.
Use of the power tool for operations different from
intended could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool
is maintained.
PRECAUTION
Keep children and infirm persons away.
When not in use, tools should be stored out of reach
of children and infirm persons.

2. Power switch
Ensure that the power switch is in the OFF position.
If the plug is connected to a receptacle while the
power switch is in the ON position, the power tool
will start operating immediately, inviting serious
accident.
3. Extension cord
When the work area is removed from the power
source. Use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
4. Mounting and dismounting of the bit.

Fig. 5
5. Selecting the appropriate drill bit
䡬When boring concrete or stone
Use the drill bits specified in the Optional
Accessories.
䡬When boring metal or plastic
Use an ordinary metalworking drill bit.
䡬When boring wood
Use an ordinary woodworking drill bit.
However, when drilling 6.5 mm or smaller holes,
use a metalworking drill bit.
6. Confirm the direction of bit rotation (Fig. 6)
The bit rotates clockwise (viewed from the rear
side) by pushing the R-side of the reversing switch
lever. The L-side of the lever is pushed to turn the
bit counterclockwise.
Fig. 6
CAUTION
䡬Never change the direction of bit rotation during
operation.
Turn the power switch OFF before changing the
direction of bit rotation; otherwise, the motor will
burn.
䡬Always use with clockwise rotation, when using it
as an impact drill.
7. Side handle attachment
Attach the side handle to the mounting part.
Rotate the side handle grip in a clockwise direction
to secure it.
Set the side handle to a position that is suited to
the operation and then securely tighten the side
handle grip.
8. IMPACT to ROTATION changeover (Fig. 7)
The impact drill can be switched from IMPACT
(impact plus rotation) to ROTATION (rotation only)
by simply sliding the change knob. When boring
concrete, stone, tile or similar board materials, slide
the change knob right. The drill head impacts against
the material while continuing to rotate.
When boring metal, wood or plastic, slide the change
knob fully to the left. The drill simply rotates as
an ordinary electric drill.

CAUTION
Do not use the impact dril in the IMPACT mode
if the material can be bored by rotation only. Such
action will not only reduce drill afficiency, but may
also damage the drill tip.
When changing over, ensure the change knob is
slide as far as it will go.
9. High-spped/Low-speed changeover
To change speed, rotate the gear shift lever as
indicated by the arrow in Fig. 8. The numeral “1”
engraved on the drill body denotes low speed, the
numeral “2” denotes high speed.
Fig. 8
PRACTICAL HANDLING PROCEDURES
1. Speed adjustment and switch operation
䡬The drill speed can be adjusted from 0 through full
speed by regulating the trigger-squeezing force.
The more the trigger is squeezed, the faster the drill
rotates. When the trigger is squeezed fully, the
speed is the maximum.
䡬Pulling the trigger switch and pushing the stopper,
keeps the switched-on condition which is convenient
for continuous running. When switching off, the
stopper can be disconnected by pulling the trigger
again.
CAUTION
Drill at a maximum rotation speed when drilling
wooden materials.
2. When using as a Drill or an Impact Drill
(1) Pressing force of the drill
You cannot drill holes more quickly even if you
press the drill with a stronger force than necessary.
It not only damages tip of drill bit and decreases
the efficiency of operation, but also shortens the
life of the drill tip.
(2) In case of penetrating holes
Drill bits can be broken when the material being
drilled is penetrated. It is important to decrease
pressing force just before penetrating.
CAUTION
In continuous operation, conduct no-load operation
for five seconds after completing a drilling job.
(3) When a thick drill bit is used
Your arm is subjected to larger reaction force when
a thicker drill bit is used. Be careful not to be moved
by the reaction force. For this, establish a foothold,
hold the unit tightly with both hands perpendicularly
to the material being drilled.
Gear shift lever
3. Using a large diameter drill bit
The larger the drill bit diameter, the larger the
reactive force on your arm. Be careful not to lose
control of the drill because of this reactive force.
To maintain firm control, establish a good foothold,
hold the drill tightly with both hands, and ensure
that the drill is vertical to the material being drilled.
4. When drilling completely through the material
When the drill bit bores completely through the
material, careless handling often results in a bro-
ken, drill bit or damage to the drill body itself due
to the sudden movement of the drill. Always be
alert and ready to release pushing force when drilling
through the material.
MAINTENANCE AND INSPECTION
1. Inspecting the drill bit
Continued use of a worn and/or damaged drill bit
will result in reduced drilling efficiency and may
seriously overload the drill motor. Inspect the drill
bit frequently and replace it as necessary.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very “heart” of the
power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or
water.
4. Servicing
Consult an authorized Service Center in the event
of power tool failure.
